I've been using Tixati for a while now on windows.I've switched to linux and was pleased to find that its supported on there as well. The only thing is is that when I switch my GTK skin using
 lxappearance

I get this error

(tixati:24342): Gtk-WARNING **: gtk_scrolled_window_add(): cannot add non scrollable widget use gtk_scrolled_window_add_with_viewport() instead
tixati: cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: Assertion `!scaled_font->cache_frozen' failed.
Aborted (core dumped)

It seems to work with certain themes but unfortunately it don't with the ones that I like.

If anyone had any information is appreciated.

Send that core dump to the devs with small explanation. support@tixati.com
